CAR-COUPLING.

SPECIFICATION forming part oi Letters Patent No. 296,005, dated April 1,1884.

Application led January 15, 1884.

(No model.)

ATo all whom it may concern,.-

Beit known that l, FRANK J. HETZNEE, a citizen of the United States, residing at Rochester, in the county of Fulton and State of Indiana, have invented a new and useful Car# Coupling, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to car-couplings; and it has for its object to provide a device of this character which shall be cheap and simple in The invention consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure l is a perspective view of a car having my improved coupling applied thereto. Fig. -2 is alongitudiual section of the same. Fig. 3 is a bottom View, and Fig. 4 is a modification.

A represents the car, to the under side of which is secured a bumper, B, ofthe ordinary construction.

C represents the draw-head, which is secured within the bumper B. The rear end of said draw-head is recessed or cut away, and

upon saidrecessed portion is mounted a coilspring, a, the rear end of which bears against a cross-beam, b, of the bumper B, and the forward end against the ledge formed upon the draw-head by recessing or cutting away the same. A transverse pin, c, is employed to prevent the forward movement of the draw. The draw-head C is` provided with the usual link or hook opening, d, which extends rearwardly nearly the entire length of the drawhead. VVithinthe draw-head, and at the rear end of the same, is secured the rear end of a `spring Vcoupling-latch, D. The forward end is situated atthe front end of the draw-head, and is provided with a hooked portion to receive l andretain the coupling-hook. Upon the upper side of the draw-head, and at about the center of the same, is located a longitudinal slot, e, which communicates with the drawhead. This slot or opening is adapted to re` ceive a rod extending downwardly from the top `of the car, said rod depressing the spring couplinglatch to uncouple the cars by means to be more fully described. i

F represents the rod for uncouplin g the cars,

the same being mounted in a bracket, f, secured to the outer side ofthe car and passing through a perforation in the bumper `and entering the slot in the draw-head. Upon the bracket f, and at the outer end of the same, is mounted a standard, f', having arms f2 at its top, between which is pivoted the endl of aleprovided on its rear side with teeth h, for a purpose to be described. y

I represents a bell-crank lever, which is pivoted near the rear end of the lever G, and is provided with a perforation, h, to receive the bent end h of a rod, h2, carrying at its end a block, h3, which engages with the teeth upon the standard H. Upon this rod hl is mounted a coil-spring, h4, which bears against the end of the Vblock h3 at one end and againstablock, h5, at the `other end, said block being secured to the side of the lever G, and having a perforation for the passage ofthe rod h2.

In applying my coupler to platform-cars, I employ a screw-threaded rod secured in a screw-threaded bracket to the front of the car, whereby the coupling-latch is depressed to uncouple the cars by turning the end of the rod down upon the coupling-latch. T The rod, as it will be obvious, need not be screw-threaded its entire length, but only a sufficient distance to allow of the ready working of the same.

The operation is as follows: The link of the adjacent car strikes against the coupling-latch coupling-hook'to be removed.

From the foregoing description it will be apparent that by the` use of my improvements.

the operation of couplingis rendered certain, and that the devices for uncoupling the cars IOO are also certain and effective in their operation.

I Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a car-coupling, the combination, with a draw-head, of a coupling-latch provided at its front end with a hooked portion, and a spring-pressed rod extending upwardly from the under side of the ear and passing through the rear end of said latch, substantially as set forth.

2. The combination, with the draw-head having a coupling-latch secured therein, of a rod mounted in a bracket secured to the outer side of the car, a standard secured to said. bracket having arms, between which is pivoted one end of a lever, said lever being also connected to the coupling-rod, a standard, H,

vhaving teeth h, a bell-crank lever, I, pivoted ing provided With a coil-spring, which bears against the block h3 at one end and against the block hf" at the other end, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two Witnesses.

FRANK JOHN HETZNER.
